Transformer oil common problems and solutions

I. How many anti deterioration measures are widely applied for Transformer oil?

To extend the oil service life, periodical maintenance work should be done carefully. There are 3 kinds of anti deterioration measures for Transformer oil:

1)    Use oil purifier machine remove the water, gas and impurities in transformer oil thoroughly.

2)    Add T501 antioxidants in oil.

3)    For more than 1000KVA transformer,  following anti deterioration solutions are recommended strongly:

a)    The new oil and regenerated oil should include T501 not less than 0.3% ~0.5%. , the operating oil not less than 0.15%, when the content is lower than the prescribed value, should be added. When add T501, it should keep the oil PH value not less than5.0.

b)    Install the thermosyphon, the adsorbent dosage should be 0.5%~1.5% of the amount of oil.

c)    Installation of diaphragm seal device.  

II. How to treat the Transformer oil containing various impurities?

follow methods is recommended:

1)    Filtering:  remove fiber, carbon residues, metal and other particles, sludge and other solid impurities.

2)    Heating:  separation of dissolved and free moisure.

3)    Vacuum pumping:  remove dissolved air and other gases.

 

FuooTech Series ZYD Double-stage vacuum transformer oil purifier is special for treating the new and old transformer oil. This machine adopts the double stages vacuum system, which can improve the machine working vacuum value highly, so it can remove the water, gas and impurities in transformer oil high-efficiently, increasing and maintain the oil's dielectric strength and quality of oil, make sure the electric device running safely.

Meanwhile, as the bridge-type vacuum linking system, FuooTech Series ZYD Double-stage vacuum transformer oil purifier can be used as independent vacuum source with functions of vacuum drying, vacuum filling oil for power Transformer.
